Abstract

An electrode part having a color different from that in the other part in a module is covered and concealed without increasing the number of steps necessary for assembling a solar battery module to render the color of the whole CIS-type thin film solar battery module uniform and thus to improve the appearance. By virtue of rendering the color of a submodule (3) and the color of the submodule in its electrode part (3A) identical to each other, a solar battery module (1) has a good appearance. A black ceramic layer (7) having a color substantially identical to that in the submodule (3) is formed on the backside (lower surface) of the edge in a cover glass (4). The silvery white electrode part (3A) provided on the outer periphery of the submodule (3) is covered and concealed by the black ceramic layer (7). As a result, the whole module (1) has a uniform color and thus has an improved appearance. The black ceramic layer (7) is baked by taking advantage of heat in strengthening by heat treatment of the cover glass (4).
